Hi, after melting the white chocolate do I add it immediately into the beaten butter? For me I think the chocolate was too hot and it melted the butter which was previously beaten till light and fluffy. Should I cool down the chocolate first?

Hi Stella, thank you for visiting my blog :D
This butter cream filling should be a quite thick (not fluffy) texture, but yes, it’s better to wait cool down the chocolate a bit first. Thank you for pointing out this method!

Thanks for this recipe!! Been looking around for this recipe after trying it from a Japanese Bakery and finally found it! Gonna try making them tomorrow, I’m not really into the rum taste though, can I cut that part?

Thank you for your comment Sheon! I love this cookies too :)
Yes, you can cut the rum part or maybe it would be nice to use a few drops of vanilla extract instead of the rum. Hope you’ll enjoy the cookies tomorrow!
